BUBGLAR 'ALARM.

Be it known that we, -WILLIAM D. Htn PETI'I and CHARLES C. HanTzoon.citizens of the United States, residingat Monroe, in the parish ofOuachita and State of Louisiana, have invented new and usefulImprovements in Burglar-Alarms, of which the followingis aspecification.

This invention relates to burglar alarms, the object of the inventionbeing to provide a simple, reliable and effective device foraudiblyindicating when a window sash or Specification of Letters Patent.

Application filed June 19, 1912.

' minal door has been opened, the'devi'ce being applicable to theordinary sash arrangement used in windows, and being applied easily byany unskilled person.

A further object of the invention is to provide means whereby during theday time the operativeparts of the alarm may be thrown out of operativerelation to each. other, so that the sashes may be raised. and lowered,without interfering wit-h thealarm mechanism.

Vith the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts, as will behereinafter more fully described, illustrated in the accompanyingdrawings, and pointed outin the'claims hereuntoappended. I

In the drawings: Figure 1 is a vertical cross section through themeetingrails of a pair of sashes, showing the alarm applied thereto. Fig. 2 isa View in elevation of the same. Fig. 3 is an enlarged detail view,showing the main parts of the alarm tripping mechanism in their relationto each other. Fig. 4 is a detail view of the hinged and folding lug.

Referring to the drawings, 1 designates the bottom rail of the uppersash, and 2 the top rail of the lower sash.

The burglar alarm embodies a base plate 3. provided with any suitablenumber otj holes c adapted to receive screws or like, fasteners, wherebysaid plate is secured to the inner face of the meeting rail 2 of thelower sash, in a manner illustrated in Figs.

1 and 2; Extending outwardly from the l base plate 3 is the post l of arotary hell 5, 5

containing suitable mechanism, such as a hammer and actuatingIllOCllEllllHll therefor, 5 whereby when he hell released and 11- llowed to he revolved by the usual spring. the l bel is sounded.Extending upwardly from Patented July 22, 1913-. eel-n1 No. raises.

the bell a plunger trip or rod 6 which, when pressed downward or towardthe center, of the bell. releases the mechanism which causes the bell tobe sounded. Extending outwardly from the top of the plate 3 is a bracket7 having an upwardly extending ter portion 8, upon which is pivotallymounted, at 9, a sleeve 10, through which passes a lever 11, the samebeing threaded to receive one or'more nuts 12 and 13, by means of whichthe lever 11 may be adjusted 'in the direction ofits length, forapurpose which will hereinafter appear. The bracket 7 is also providedwith a guide opening 14, through wh ch the plunger trip 6 is arranged"to slide. as shown in Fig. 1, said trip being normally upheld hymeansof a coiled spring- 15 which. extends around the plunger trip (3 and isinterposed between the bracket 7 and a head or shoulder 16 at the upperend of the plunger rod. The lever 11 rests upon thehead 16 of theplunger, so that when said lever is depressed, the plunger iscorrespondingly depressed, thereby'releasing the mechanisln whichactuates the bell Connected to the bottom rail 1. of the upper sash isan outwardly projecting lug 17 which cooper ates with the extremity ofthe lever 11, for depressing thelever, either when the uppef or lowersash is opened.

.In the preferred embodimentof this invention, the lug 17 is hinged at18 to a bracket or attaching plate 19secured to the rail 1 of the uppersash, as by this arrangement the lug 17 may be folded back against thesash or into arecess in the face of the sash, so as to be out of thepath of the lever 11, thus enabling the device to be thrown out ofuse inthe day time. Furthermore, the lever ll may be moved outward in thedirection of its length. so as to carry the inner end thereof out of thepath of move' ment of the lug 17, even when it is in a projectingposition, as shown in. Fig. 1. Either of the adjustmentsreferred to willthrow the device out of operation in the day time. when it not needed.and either one of said elements will enable the device to be thrown intooperation, when desired. If desired. a set screw 20 may be used forfixing the adjustment of the lever 11 in the l CQ\'O 10.

What is claimed is: I

1 ln a burglar alarm. a rotary bell, a

,plate on whicn said bell is supported, a

bracket on said plate, a lever fulerumed on said bracket,- a plungerarranged to be operated by said lever and adapted to trip the bellactuating Inechanism, anda lug with which the lever isj'adapt'ed to comeinto conplate on-which said bell is supported, a

bracket on said plate, a lever fulcrumed on sand bracket, means foradgusting said lever in the directionv of its length, a plunger arrangedto be operated by said lever and 15 adapted to trip the bell actuatingmechanism, and a lug with which the lever is adapted to come intoeontact upon movement of the sash in connection with which the alarm isused.

In testimony whereof we aifix our signatures 1n presence of twowitnesses.
